Overview

AI-generated overview

A local MCP server that gives an assistant aggregate structural counts of a project's test suite without exposing test names, paths, or code.

What you can do
  • Inspect a local project's test suite structure with a single tool, inspect_test_shape.
  • Get aggregate counts of test blocks, suites, async tests, assertion-bearing files, and empty test bodies.
  • Review the shape of a test suite for triage without seeing test names, paths, source, or assertion details.
When to use it
Useful when you want a quick, privacy-preserving overview of how a local test suite is structured, for example to spot empty test bodies or files with assertions before a review. It is a triage aid, not a substitute for running the tests.
Requirements
Runs as a local process over stdio, installed from the npm package test-shape-mcp; a Node.js runtime and a local project with test files are needed. No authentication, environment variables, or headers are declared.
Before you install
It reads bounded local test files on your machine, though responses are limited to aggregate counts and suppress test names, paths, and source. Results are heuristics for review triage, not a replacement for running tests.

Installation

In SourceWeft

  1. Open Test Shape Mcp in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

test-shape-mcp

Test Shape gives a quick structural view of a local test suite. It counts test blocks, suites, async tests, assertion-bearing files, and empty test bodies without exposing test names or code.

Quick start

bash
npm installnpm testnpm start

Use inspect_test_shape against a local project. Results are heuristics for review triage, not a replacement for running tests.

Privacy and limits

Only bounded local test files are read. The response contains aggregate counts only. Test names, paths, source, and assertion details are suppressed.

Score

40% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.

  • Tools listed15 pts

    Answer tools/list without a credential, or ship a package that starts in a sandbox without one.
